11月11日(ri)(ri)，西(xi)北(bei)電網(wang)外(wai)(wai)送(song)電量達到1.051億千瓦(wa)(wa)時，單日(ri)(ri)外(wai)(wai)送(song)電量首次突破1億千瓦(wa)(wa)時大(da)關，外(wai)(wai)送(song)最大(da)負(fu)荷達511萬(wan)千瓦(wa)(wa)，占(zhan)目(mu)前西(xi)北(bei)外(wai)(wai)送(song)總(zong)容量的83.63%，日(ri)(ri)外(wai)(wai)送(song)電量和外(wai)(wai)送(song)負(fu)荷均創歷史新高。
隨(sui)著(zhu)寧(ning)東—山東±660千伏(fu)直流輸(shu)電(dian)(dian)示范工程順利投入試運(yun)行，西(xi)北電(dian)(dian)網外送(song)最大容量達(da)到611萬(wan)千瓦，西(xi)北外向型(xing)、送(song)出型(xing)、規(gui)模型(xing)堅(jian)強送(song)端電(dian)(dian)網已(yi)初具規(gui)模，實現(xian)西(xi)北—華北、西(xi)北—華中聯網，將黃河(he)上游水(shui)電(dian)(dian)、煤電(dian)(dian)基地(di)火(huo)電(dian)(dian)打捆送(song)往四川、山東，有力推進西(xi)北能(neng)源資(zi)源在更大范圍內優(you)化配置，為緩(huan)解冬季華中、華北電(dian)(dian)網缺電(dian)(dian)局面提(ti)供了強大的電(dian)(dian)力支撐。
為應對外送(song)負荷和(he)網內用電(dian)(dian)負荷高峰的到來，確保迎峰度冬和(he)大負荷外送(song)期間電(dian)(dian)網安(an)全穩定(ding)運(yun)行，西北電(dian)(dian)網有(you)限公司加快全網檢修和(he)設備投(tou)產速度，目前已(yi)實(shi)現(xian)750千伏統一電(dian)(dian)網覆蓋西北五(wu)省（區），強化了西北送(song)端(duan)網架結構。
西(xi)北公司還指導主(zhu)要火(huo)電(dian)(dian)發(fa)(fa)電(dian)(dian)企業(ye)簽訂(ding)了(le)年利(li)用(yong)5000小時以上(shang)的中(zhong)長期(qi)(qi)合同(tong)，以黃河富(fu)余(yu)水電(dian)(dian)進行(xing)短期(qi)(qi)調節，充分發(fa)(fa)揮“電(dian)(dian)量庫”交易機(ji)(ji)制，提前(qian)做好外(wai)送(song)電(dian)(dian)力(li)電(dian)(dian)量組織工作(zuo)。同(tong)時，密(mi)切關注天(tian)氣變(bian)化，提高負荷預測(ce)的準確性，合理(li)安排機(ji)(ji)組開機(ji)(ji)方(fang)式，加大電(dian)(dian)煤(mei)儲運工作(zuo)力(li)度，提前(qian)落實全網(wang)發(fa)(fa)用(yong)電(dian)(dian)平衡。此(ci)外(wai)，西(xi)北公司還將440萬千瓦火(huo)電(dian)(dian)裝(zhuang)機(ji)(ji)列入外(wai)送(song)裝(zhuang)機(ji)(ji)序列，協調西(xi)北區域內(nei)主(zhu)要水、火(huo)電(dian)(dian)廠留足備用(yong)容(rong)量，提前(qian)做好電(dian)(dian)力(li)電(dian)(dian)量平衡工作(zuo)。
